So I'm playing my first USTA Flex League and I ran into a situation in my last match, and was wondering what the correct etiquette was. We went through our warmup as usual, and when we got to serves, I did mine, but then my oppenent said he had warmed up his serve before he got to the court and didn't want to hit any. I didn't make a big deal over it. But as we started the match, he had kind of a funky service motion, and it took me about 3 or 4 of his service games to get comfortable, as well as get used to the lighting on the new court. I ended up winning the match, so it wasn't a real big deal, but I'm wondering if he should have done warmup serves, if nothing else than to give me a chance to receive on a court I've never played before? Thoughts?
